Technically, to lift the LX570 via AHC correctly, should involve shimming the springs. When I say correctly, it’s to ensure that the new higher position still maintains the same payload capacity as the factory position. AHC on the 200-series has proved much more robust with more capacity than the 100-series, so most people don’t notice the drop off in payload. And there’s no easy torsion bar adjustment to dial in ideal neutral pressures.
It really wouldn’t be too hard to find spring spacers. The rear is easy peasy. I have 10mm ones in mine. 30 minute install. The front would be more tedious to remove the shock/spring, but still would be doable. No one’s tried, so we don’t know the dimensions of the needed front spacer. There’s likely compatible spacers readily available.
I have 10mm spacers on my rear, not because I lifted AHC. It’s because I’ve gone much higher loads than rated payload (~1350lbs). To 1800lbs towing 1000lb tongue weight, with 6 people on-board, so it was out of an abundance of caution, that I added shims to best support AHC.
In regards to lift, I didn’t bother. Comparing to older vehicles it's not really apples to apples. No old cruiser will handle and corner like a new 200-series, and would likely flip if they could generate the same cornering grip of the modern cruiser (e.g. moose test). I did a real lift via taller tires (33.2”) to lift everything including axles by ~1”. I drive my LX rather hard on roads, so I wanted to maintain excellent handling (including 305 section tires). Suspension lifts change the suspension angles, impacting toe control/roll resistance/everything. So it was important to me to keep it optimal. I offset the increase in COG with tire lift by adding 1" wheels spacers to add some track width and regain lateral stability. Besides, with AHC, I can lift when I want anyways. It’s been unstoppable on road, and off.
